I just completed the Cessna disks, which featured the Kings, so I took the "non - towered communication" course, and actually both were excellent. Of course, I have reservations about some of their courses, as the radio section in the Cessna package, and this course, utilized outdated radio technology. Things do need constant updating with the speed the world changes -- even VOR is disappearing in favor of GPS.
